I need help figuring out why my '82 RM250 isn't getting any spark. This past few days has been frustrating, I went to friends house on my bike. When I decided to leave I couldn't get my bike to start. At first I thought it was flooded so I had my buddy try pull starting me. I still wasn't able to get the bike to start, my buddy ended up dragging me and my bike home, the next day I went to start it, wouldn't start so I started working on it, I checked to see if It was getting fuel, It was. Also checked to see if It was getting spark, it wasn't getting spark. I replaced the spark plug with a brand new one and It still wasn't getting any spark. I also looked at the wiring for any damage, couldn't see any. also looked at the magneto, its got some rust, it was also a little wet in a couple spots. I dried it off and checked to see if it was getting any spark. Still nothing.
Not getting spark
- Thread starter RichyRich23
- Start date
Also check all the harness connectors, some times they look like their plugged in but may not be.
All good advice. Sounds like my problem as well. I've got a 94 rm125 was running great and parked it for the night. Next day wouldn't start, found it wasn't getting spark. So I started working my way thru the possibilities. Ended up buying a new coil (after spark plug and redoing all my connections) fired right up. Went to touch the spark plug wire and shocked the #! $@ out of me. Killed the bike and to check why and now the bike hasn't fired up again since. I replaced the stator and still nothing. I'm thinking its the cdi but jeez they're expensive or i can't find a used one anywhere. (The internet)
I raised one of those (a/p's). I used to give him things he had to put together, and reading the manuals (SRAD and I talked about that at length) is as you say the ONLY way to properly do your job. I didn't realize what I started 30 years ago, I was just trying to force him to read. But you well understand why I asked.
Update. After much work do to impatience and not having the correct tools. I finally messed enough stuff up to warrant getting a and new magneto, cool, cdI box. Got everything zipped tight. And it fires right up. CDI box was indeed the issue.
another update... so i got it going. loaded it up on the truck and went to my local riding area. after no joke 5 min of riding it quit on me. so i swallowed my anger and pushed it back to the truck. Upon inspection it was yet again a no spark issue. At this point I've replaced and rewired the entire bike. Confident it wasn't the CDI box i popped open the stator cover and found it was shorted out. I bought the part off eBay because i didn't have nor did i want to spend the extra money on a OEM part. Luckily it has a 1 yr. warranty on it. Keep you posted when i get the part in sometime next week.
Ok. After the 2nd replacement stator burnt up after 10 min of riding. I scoured ebay and found a used OEM stator. Ordered that, installed and behold! It works and better yet has continued to run perfectly. Lesson to learn from all this... #1 have the right tools for (insert job) #2 always go OEM, even if its a 22yr old part.
Yep. Even better. If you can find an airport local that will rewind staters. Go there.
